Using this topic as an example: You topic ID is `44239`.

A `GET` to `https://meta.discourse.org/t/44239.json` returns an object where `post_stream.posts[0].id = 194190`.

I then liked your post by `POST`ing to `https://meta.discourse.org/post_actions` with `id=194190&post_action_type_id=2&flag_topic=false`. This request needs to be authenticated by an API key or cookies.
